The 1286 has been sold by a couple of small companies, mostly in Europe I think, almost as long as the 1003/1266 has been out. This is the first I’ve heard about Carbonda offering single frames to the general public but maybe nobody’s asked in a long time?
My guess is that it handles pretty similarly to the 1003…I wonder how the kinematic graphs compare. For me at 205-215lbs I need an air shock at close to max pressure for the 1003 and I wonder if I’d be happy with a coil shock for supportive park riding/jumps on the 1286 or not.
Would love to build one up someday if I start riding more park, but the 1003 is already plenty of bike for me (if not overkill) on 99% of New England stuff that I actually want to ride — even park.
